Given:

The decimal number 1.42

To find:

The fraction and percent.

Solution:

Writing 1.42 in the fraction form:

In the given picture 100 small box makes 1 whole number.

Therefore

Denominators are same, so you can add the numerators.

Converting improper fraction into mixed fraction.

Writing 1.42 in the percent form:

1.42 = 100% + 42$

      = 142%

1.42 = 142%

what?

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
